Abstract (en)
[origin: EP1281383A1] A dental material based on a polymerizable binder containing at least one chromophoric silica-metal oxide xerogel (I) as coloring component, is new. A dental material based on a polymerizable binder contains at least one chromophoric xerogel of formula (I), (SiO2)a(SiO1.5-Sp-X-CG)(MenOm)b (I) Me = a main group II or III metal or a group IV transition metal; n = 1 or 2; m = 1 or 2 when n =1, and m = 3 when n = 2; Sp = 1-10C alkylene or 2-10C oxyalkylene with 1-4 oxygen atoms; X = a connecting group CO-O, O-CO, CO-NH, NH-CO, O-CO-NH, NH-CO-O, NR, O or S, where R = H or 1-6C alkyl; CG = a chromophore; a = 0-20; and b = 0-5. Independent claims are also included for the following (1) a chromophoric xerogel of formula (I); (2) a process for preparation of the chromophoric xerogel by hydrolytic condensation in the presence of one or more metal alkoxides.
